WHAT IT DOES

What cli_is_installed does on Mcp Anything

AI agents call cli_is_installed to retrieve information from Mcp Anything without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why cli_is_installed is rated Low

This tool performs a simple presence/installation check on a CLI harness, which is a read-only operation with no side effects. It queries system state but does not create, modify, delete, or execute operations. The low severity reflects minimal blast radius—an incorrect result only provides false information about installation status.

From the tool's definition Tool name 'cli_is_installed' and description 'Check whether a CLI-Anything harness is installed' indicate a query operation that retrieves status information without modifying any state.
